Lotus 1-2-3 1.x

Lotus 1-2-3 was an early spreadsheet application available for MS-DOS. It became extremely popular in the late 1980s, displacing the former leader VisiCalc. Lotus had difficulties adapting 1-2-3 to the Windows environment, and was overtaken by Microsoft Excel. Later versions were included in Lotus SmartSuite.

The 1.0A* (star) releases below are of several later copy protection variations. An unprotect exist for one, but not the other. However, these include flux and CopyIIPC disk images that will recreate a functional disk.
